Quantum simulator gives clues about magnetism

Researchers optically trapped a cloud of gas a billion times colder than air in a very low-pressure vacuum, and found a lower speed limit to diffusion. Assembling the puzzles of quantum materials is, in some ways, like dipping a wire hanger into a vat of soapy water, says one of the researchers. Long before mathematical equations could explain the shapes and angles in the soap foams, mathematicians conjectured that soap films naturally found the geometry that minimized surface area, thus solving the problem of minimal surfaces. They could be created simply by blowing soap bubbles.
